AH HA...darn. I RACED to get back to the forum so I could answer my own question. Too late!
Ok , I replaced the batteries once already just because I figured it was time. No other indication that they were needed. That has been about 2 mos ago. Anyway , I tested the cells today and they were all @0.9v ! I installed new ( 1.5v ) cells and quess what. No beeping. I never thought that this little "toy" tx could be that smart! When my Futaba 9c beeps like that............low batteries! It dawned on me after a couple hours. duh
So there you have it kids. Go out and get you some rechargeable cells and save money in the long run.
